If it happened, I'd buy it depending on the games and price. But they'd need to wrangle a lot of licensing deals to happen so it's not going to happen. I'd want Link Faces of Evil and Hotel Mario from Nintendo. Then you'd have digital leisure with Dragon's Lair and Space Ace. The other random scatter shot stuff like Mutant Rampage Body Slam, Lords of the Rising Sun, Little Divil, Escape from Cyber City, Namco Museum, Tetris, Pinball, Kether, Voyeur, Burn Cycle, Chaos Control are just 15 games off the top of my head I think would be a nice collection.
I kind of doubt Nintendo'd give them the rights to include those games; they're very protective of the brand image of their IPs and even if hardcore gamers know those games as the jokes they are, putting them out there again officially could give a bit of a sloppy look to those IPs to those who don't know better...assuming a CD-i Mini ever got enough traction to get big mainstream numbers.
You've certainly done a way better job coming up w/ a list than I ever could for the this system, tho.
Would there be any interest in a combined Sega CD and 32X mini? They're part of Sega's history and there are some fun games for those systems.
Tbh they can kind of do this already with that upcoming MegaDrive Mini. Maybe just do a version that looks like a combined unit (well, maybe not the Frankenstein version, maybe base it off the CDX or that CD/32X prototype design maybe).
...Hey, with ATGames out of the picture, my hope's renewed on this one xD
